Protein Donut Ingredients

  • Vanilla Protein Powder- Use your favorite protein powder, whether that’s plant-based or whey protein. Be sure you like the flavor of the protein powder you’re using!
  • Baking Powder- This adds lift and creates fluffy donuts.
  • Salt- This balances out the sweetness.
  • Sprinkles- The sprinkles are optional but they do make these festive!
  • Oat Flour- You can make your own oat flour by blending instant or whole grain rolled oats into a flour consistency.
  • Egg- An egg helps bind the donut together and adds moisture.
  • Vanilla Almond Milk- I used vanilla almond milk but plain almond milk or dairy milk is fine, too.
  • Plain Yogurt- I prefer the flavor of plain yogurt, but you can substitute it for Greek yogurt if you prefer.
  • Cake Batter Extract- This is optional, but it gives these donuts the best birthday cake flavor!

How to Make Protein Donuts

What’s the Best Protein Powder to Use?

Honestly, any type of protein powder should work just fine for these donuts. The vanilla protein powder helps add a hint of sweetness along with the extra protein. I think whey protein gives you the best texture but use whatever protein powder you prefer.

Storing and Freezing Protein Donuts

  • To Store: the donuts will keep best stored in an airtight container in the fridge. They should keep for about a week if stored properly.
  • To Freeze: place the cooled donuts in a Ziploc bag and store in the freezer. They should last for at least 3 months. Simply let them thaw in the fridge when you’re ready to enjoy them.
